The device forming the subject matter of this application is adapted to be employed for repelling burglars or other wrong doers, the device being capable of being hidden 5 within the clothing of the wearer, for the most part, and being noiseless in operation, it being possible for the wearer to blind or strangle the burglar, thereby rendering him more or less incapable of carrying out his 10 purpose. 7

It is within the province of the disclosure to improve generally and to enhance the utility. of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from. the spirit of the invention.

Figure 6 is an elevation of the structure shown in Figure 5;

Figure 7 is an end elevation showing one of the arm bands and attendant parts;

Figure 8 is a section on the line 88 of Figure 5.

In carrying out the invention, I provide a reservoir 1, shown best in Figures 2, 3 and 4. The reservoir may be of any desired shape. It'is suggested that it may be in the form of a canteen, having eyes 2, adapted to receive straps 3, whereby the reservoir may be suspended from the body of the wearer, underneath his clothing: although the reservoirmay be mounted in any other convenient a liquid which will be repellant to a human being, and with this end in view, to facilitate the filling of the reservoir, the same is provided with a hermetic cap 4:. In order to facilitate the expulsion of the liquid in the reservoir 1, the reservoir carries an air pump 5 of any desired kind, accessible from without the reservoir. In the reservoir 1 is mounted a holder 6 of tubular form, adapted to contain a glass vial 7 or other container for acid, it being possible to introduce the vial readily into the holder, because the holder extends outwardly of the reservoir and is provided on its outer end with a removable cap 8.

At this point it may be stated that the liquid in the reservoir 1 may contain a salt, which, combining with the acid in the vial 7 when the vial is broken, produces enough gas to bring about the ejection of the liquid in the reservoir. If the operator desires, he can cause the liquid to be ejected by building up a retained airpressure in the reservoir 1, through the instrumentality of the pump 5, the acid reaction being omitted. There is no reason, however, why the operator cannot have the acid reaction, and the pressure from the pump 5, also, if he wishes.

A means is provided for breaking the vial 7, to release the acid, as and for the purpose hereinbefore set forth." Having this consideration in mind, a partition 9 is secured in the reservoir 1, the partition being provided with ears 10 on which is pivoted at 11, a loopshaped hammer 12 having a projection 14 which is prominent enough, and so located, as to smash the vial 7, when the hammer 12 moves to the right from the position of Figure 3. About the lower portion of the hammer 12, between the cars 10, is located a coil spring 15, shown best in Figure 4:, one end of the spring engaging one side arm of the hammer 12, as shown in Figure 3, and the opposite end of the spring bearing on the partition 9. The function of the spring 15 is to swing the hammer 12 to the right, from the retracted position of Figure 3.

At 16, I pivot a sickle-shaped trigger 17 in the reservoir 1, and when the hammer 12 is pulled back to the position of Figure 3,

way. The reservoir 1 is adapted to contain the upper part of the hammer will engage automatically with the upper part of the trigger, the trigger thus being held set. The upper part of the hammer 12 is rendered accessible, for setting, by taking off the cap 4. The trigger 17 is moved, to release the hammer 12, by means of an operating member 18, slidable in a gland 19 on the reservoir 1, the lower end of the operating member 18 being pivotally connected with the lower end of the trigger 17.

Externally of the reservoir 1, a flexible element 20 is connected to the operating member 18, and may be passed over a pulley21, which, as shown in Figure 1, is carried by one of the straps 3. From the pulley 21, the flexible element 20 extends downwardly along the arm of'the wearer.

On the forearm of the wearer is mounted a removable frame, which, as a whole, is designated by the nulneral 22. The frame 22 comprises'buckled arm'bands 23' and 24, connected by longitudinal strips 25. The arm band 23 has a lateral lug 26, and the arm band '24 has-a lateral lug 27. In these lugs, the flexible element 20 is slidably mounted. The forward end of the flexible element 20 is connected to a grip 28, which may be a piece of leather or'thelike, the grip having a ring 29 through which one of the fingers of the operator may be inserted, in a way which will be understood readily when Figure 1 of the drawings is noted.

The liquid outlet for the reservoir 1 embodies a flexible tube 30, connected by a nipple 31 to-the'reservoir. It .is well to attach a tube 42 to the lower end of the nipple 31, so that the .gas can accumulate on top of the liquid in the reservoir 1, and force the liquid into the tube 30through the tube 42 and the nipple 31,

though if nothing but gas is to be discharged, the tube 42 might be omitted. The flexible tube follows the general course of the flexible element 20, under the clothing of the wearer. On the forward endof the flexibletube 30 of the discharge conduit for the reservoir 1 is mounted a nozzle 32, located a little behind the hand of the operator, ordinarily, as shown in Figure l.

Figures 5 and 7 show that the'nozzle 32 is rigidly connected at 33 to an operating member 34,-in theform of a slide rod, mounted for longitudinal reciprocation in a guide tube 35-secured in the lugs 26 and 27 of the frame :22, and, specifically, mounted on the arm bands 23 and 24. The slide rod or operating member 34 is impelled forwardly by a com- :pression-spring 36 (Figure 5) located within the guide tube 35.

The slide rod 34 is' held in the retracted position of Figure 5 byaspring latch 37 carried by a bracket block 38 on the guide 35.

Arel'easing member for thelatch 37 is provided, and this releasing member, in substance, is a bell crank lever. Figure 8shows forwardly, beoause-thenozzle is connected that the releasing member comprises a loopshaped arm 39, straddling the guide tube 35, the flexible element 20 being connected to the outer end of the arm 39. The arm 39 is se-- cured to a shaft 40, mounted to rock in the block 38 on the guide 35. To the shaft 40 is secured an arm 41, shown in Figures 5' and 8, the arm 41 being disposedat an angle to the arm 39, and the arm 41 lying between the latch 37 and the guide tube 35.

With the-parts arranged as shown in Figure 1, but with the forearm of the operator 'poin'tecl'toward the person who is to be warded ofi, the operator straightens out one of his fingers, which is engaged by the ring 29,

the grip .28 transmitting longitudinal .movement to the flexible element 20. The fiex-ible element 20 movesthe operating member 180i '12. *Vfhen the hammer 12 is releasedfrol'n the trigger 17, as aforesaid, the hammer swings to the right in Figure-3, undernthe impulse of the spring 15, and the rejection 14 on the hammer strikes the vial i7 and smashes it, the acid beingreleasedinto the reservoir 1, to rningle withthe'liquidtherein, and to produce the expelling gas, in the event-thatgas pressure is relied upon, '[The gas forces the liquid outwardly through the member 42, into the'tube'30, and the liquid passes through the nozzle 32, up'on the person who is to be repelled. At the same time that-the flexible element 20 is pulled upon, for the purpose of cracking the vial 7, the-arm39 of'the bell crank lever or releasing memberis operated, the

bell crank lever tilts, with the shaft 40-as=a fulcrum, and the arm 41 (Figure-5) of the under the impulse of the spring 36, andithe nozzle 32, along-with the tube 30,areoarried at 33 to the slide 34. This forward movement-of the nozzle 32-brings the nozz'le withr in the reach of the hand of the operator, and the nozzle may be grasped conveniently, so 5 as to direct the repelling charge in 'any 'desired direction. Moreover,by ad'vancingthe nozzle 32, as aforesaid, the nozzle ispjrominently presented,"andthere is no chance that i l thehand of the operator will interefere with .420 the flow from the nozzle.
